- an adjusting device comprising at least one rotatably supported adjusting element, wherein the relative position of the at least one engagement position relative to the actuating arm assembly can be adjusted by rotation of the adjusting element; include

Furthermore, the invention relates to a furniture product, comprising a furniture body, a furniture part movably supported relative to said furniture body, and a furniture drive of the described type for moving said movable furniture part.

The carriers of these furniture drives are usually fixed to or inside the side walls of the furniture body. The actuating arm assembly of the furniture drive is pre-stressed by at least one spring device and connected to the movable furniture part in the mounted state.

EP 3 708 753 A1 discloses a non-generic furniture drive for moving furniture flaps, in which helical springs are provided to compensate for the weight of the furniture flaps. By adjusting the counter bearing, the helical spring can be variably compressed to match the force of the helical spring to the different weights of the furniture flaps. The furniture drive further includes a torque limiting device to prevent jamming between the counter bearing and the end stop. By rotating the drive element with a tool, the counter bearing is adjustable. The torque limiting device limits the torque in the first direction of rotation of the drive element to prevent jamming between the counter bearing and the end stop. On the other hand, in the second direction of rotation of the drive element, the torque is transmitted completely.

CN 106175199 A discloses a furniture drive in which the force of a spring device can be transmitted to an actuating arm for moving a furniture flap through a double arm biasing lever.

WO 2018/192819 A1 discloses a furniture drive having the features recited in the preamble to claim 1 . The rotatable tool receptacle is arranged in the front region of the housing of the furniture drive, and the spindle nut is movable along the spindle by rotating the tool receptacle with a tool. The spring assembly is supported on the spindle nut and the force of the spring assembly acting on the actuation arm assembly can be varied due to the adjustable support of the spindle nut along the spindle.

The adjusting device of the furniture drive for adjusting the force of the spring device acting on the actuating arm assembly can generally be actuated by means of a rotary tool, for example a screwdriver. In the case of untrained and/or clumsy assembly personnel, when the rotary tool is rotated with high torque, it may happen that the engagement position of the spring device is forced into the end position and becomes jammed because excessive force is applied. These snags can often be released only with great effort, and damage to the components of the furniture drive cannot be ruled out.

If the adjustment path is large, even assemblers tend to use an electric screwdriver to operate the adjustment. Thus, the risk of damage to the furniture drive is further increased.

It is an object of the present invention to provide a furniture drive of the type mentioned in the opening paragraph, so that the aforementioned disadvantages are avoided.

According to the invention, this is achieved by the features recited in claim 1 . Further advantageous embodiments of the invention are defined in the dependent claims.

The threaded portion 17 has a longitudinal direction L. An angle between the longitudinal direction L of the threaded portion 17 and the rotational axis R of the adjusting element 19a may change when the operation arm assembly 5 moves. By means of an angularly-movable coupling device 25 , the rotational movement of the adjusting element 19a can be transmitted to the threaded part 17 . Thus, the threaded portion 17 can be set in a rotational movement, so that the engagement position 18 is movable along the threaded portion 17 .

Each movable coupling device 25 comprises at least one elastic element, preferably a folding bellows, a rubber form element, a coil spring coupling, and/or at least one gear, preferably a bevel gear transmission, and/or a joint, preferably a cross joint or cardan joint.

Preferably, the adjusting element 19a of the adjusting device 19 can be provided to face the movable furniture part 3 in the mounted state of the furniture drive 4 and to be arranged in the front area of the carrier 9 . In this way, the adjusting element 19a can be easily operated from the front with a tool.

In the illustrated embodiment, at least one shaft 28 is provided for driving the threaded portion 17, and the at least one shaft 28 is configured to be driven by the adjusting element 19a. At least one shaft 28 is displaceably supported relative to the carrier 9 in or along a guide 30, preferably a long hole. In this way, the compensating movements of the components of the furniture drive 4 caused by each movable coupling device 25 can be at least partially compensated.

Shaft 28 is arranged in or on bearing device 29 . The guide 30 is disposed on the bearing device 29 and the pin 32 fixedly supported on the carrier 9 engages the guide 30 of the bearing device 29 . In compensatory movement, the bearing device 29 is movable relative to the fixing pin 32 .

FIG. 2b shows the furniture drive 4 according to FIG. 2a in which the carrier 9 is closed by the second housing wall 9b. The first housing wall 9a and the second housing wall 9b are each configured to be flat, supported on the furniture body 2 and configured together to form a substantially cuboid carrier 9 . The housing walls 9a and 9b are spaced apart from each other in a mutually parallel relationship, and the front opening 23 is formed between the housing walls 9a and 9b. The cover 12 is disposed adjacent the opening 23 and allows passage of a screwdriver to operate the adjusting device 19 .

3a shows a side view of a furniture drive 4 with a carrier 9 . The threaded part 17 is disposed on the intermediate lever 16, and the intermediate lever 16 is pivotally supported on the carrier 9 about a fixed hinge axis 15. In the figure shown, the spring device 10 applies a minimum torque to the actuating arm assembly 5, with the engagement position 18 of the spring device 10 adjacent to the hinge axis 15 of the intermediate lever 16. because it is located A conceptual connection line between the hinge axis 15 of the intermediate lever 16 and the engagement position 18 of the spring device 10 forms a relatively short lever arm. Thus, a minimum torque acts on the actuating arm assembly 5 .

The axis of rotation R of the adjusting element 19a of the adjusting device 19 and the longitudinal direction L of the threaded portion 17 form an angle relative to each other, the angle being variable during movement of the actuating arm assembly 5 . The advantage of this configuration can be seen in FIG. 3 a , in the illustrated closed position of the furniture drive 4 , due to the angularly movable arrangement of the axis of rotation R and the longitudinal direction L, the actuation of the actuating arm assembly 5 This is because the arms 5a to 5e, together with the spring device 10 and the adjusting device 19, can achieve a very compact position relative to each other.

Thus, the adjusting element 19a and the rotatable threaded portion 17 are angularly movably supported relative to each other upon movement of the actuating arm assembly 5 . As a result, the actuating arm assembly 5 and the adjusting device 19 for adjusting the force of the spring device 10 can achieve different positions relative to each other. In this way, the components of the furniture drive 4 can be inserted into one another and thus can be arranged closer together. As a result, the furniture drive 4 can be designed more compactly, and the adjustment path of the spring device 10 in the threaded part 17 can be increased, covering a higher performance range of the furniture drive 4. can

The carrier 9 can be configured in a substantially rectangular shape, preferably the ratio of the length L1 of the carrier 9 to the height H1 of the carrier 9 is greater than 1:0.7, preferably 1:0.5 may be provided in a larger size. By means of this dimensioning, a reduced height H1 of the carrier 9 can be provided. In this way, the height of the recess 11 ( FIG. 1 b ) of the furniture panel 6 can also be dimensioned small, and the manufacturing effort of the recess 11 and the weakening of the furniture panel 6 are insignificant.

FIG. 3b shows the furniture drive 4 according to FIG. 3a with minimum force adjustment of the spring device 10 , wherein the actuating arm assembly 5 with actuating arms 5a to 5e is positioned in the open position. . It can be seen that the angle between the axis of rotation R of the adjustment element 9 and the longitudinal direction L of the threaded part 17 is reduced compared to the closed position shown in FIG. 3a .

The actuation arm assembly 5 includes a first actuation arm 5a pivotable about a first hinge axis 26 and at least one second actuation arm pivotable about a second hinge axis 27 ( 5b). The first hinge axis 26 and the second hinge axis 27 are spaced apart from each other in the longitudinal direction L2 of the carrier 9 . Compared to the first hinge axis 26, the second hinge axis 27 is disposed in the front region of the carrier 9.

The intermediate lever 16 is preferably connected directly to the second (front) operating arm 5b via a curved pushing lever 24 . Therefore, the first operation arm 5a is not directly connected to the pushing lever 24 via the hinge shaft. Instead, the first operation arm 5a is displaceably guided within the pushing lever 24 . This can be seen best in Figure 2a. In this way, the force of the spring device 10 can be improved and introduced directly into the actuating arm assembly 5 .

4a shows a perspective view of the furniture drive 4 . The furniture drive 4 includes an overload safety device 33 for limiting the maximum torque between the adjusting element 19a of the adjusting device 19 and the engaging position 18 of the spring device 10 .

The overload safety device 33 engages the adjusting element 19a with the transmission mechanism 35 when the adjusting element 19a rotates with a torque less than the predetermined torque, and the adjusting element 19a with a torque exceeding the predetermined torque The overload safety device 33 is configured to disconnect the regulating element 19a from the transmission mechanism 35 upon rotation of the motor.

In the embodiment shown, the overload safety device 33 comprises at least one spring element 34, for example in the form of a compression spring. The shaft 28 can be pressed against the adjusting element 19a of the adjusting device 19 by the force of the spring element 34 . Preferably, the shaft 28 can be provided so that it can be pressed against the adjusting element 19a of the adjusting device 19 in the axial direction of the shaft 28 .

Preferably, it may be provided that the rotational axis R of the adjusting element 19a and the longitudinal direction L3 of the at least one shaft 28 extend coaxially with each other.

Adjusting element 19a and shaft 28 can be rotatably coupled to each other via cooperating toothed arrangements 37a, 37b (FIGS. 5a to 5d). When the adjustment element 19a rotates with a torque less than the predetermined torque, the adjustment element 19a engages the shaft 28 . When the adjustment element 19a rotates with a torque exceeding the predetermined torque, the adjustment element 19a is separated from the transmission mechanism 35 . When exceeding the torque applied to the adjustment element 19a, the spring element 34 is thus compressed, and the adjustment element 19a and the shaft 28 can be separated from each other.

Figure 4b shows the frame area of Figure 4a in an enlarged view. By means of a fastening device 31 with at least one rotatable tensioning element 31a, the carrier 9 of the furniture drive 4 is clamped in a recess 11 of the furniture panel 6 ( FIG. 1 b ). can be fixed as

Figure 5c shows an overload case when the adjusting element 19a is rotated with a torque exceeding a predetermined torque. Upon exceeding a threshold torque, the adjusting element 19a and the shaft 28 rotate relative to each other. Adjusting element 19a and shaft 28 are axially spaced apart from each other due to cooperating tooth arrangements 37a, 37b, and spring element 34 is compressed. In this way, the shaft 28 can be separated from the rotational movement of the adjusting element 19a.
